Definitions

  • This invention relates to wrap-around carriers which incorporate end stops or retainers to prevent outward movement of the packaged articles. More particularly, it relates to a carrier of this type in which the retainer is compatible with the mechanical locks that connect the bottom panel flaps of the carrier to each other.
  • Wrap-around article carriers are commonly designed to have ends which are either partially or entirely open. In either case the carriers must be provided with means for preventing the articles from falling out the ends.
  • Beverage cans for example, are held in place partly by the tension applied by the carrier blank being wrapped very tightly about them and by the engagement of the top and bottom flanges of the cans with the edges of cutouts in the side panels of the carrier through which the flanges of the can extend. Bottles are more difficult to retain in open-ended carriers than cans due to their shape. Even though cutouts may be provided in the side panels of a carrier to receive the heel portions of bottles, their tapered or necked configuration makes it difficult to apply the carrier wrapper as tightly as in the case of cans.
  • U.S. Pat. No. 5,094,347 issued Mar. 10, 1992 in the name of Richard D. Schuster.
  • This patent discloses a bottle retainer or stop at each end of the bottom panel which extends between the curved spaced portions of adjacent end bottles.
  • the stops are formed from retainer tabs in the outer bottom panel flap which are folded into final shape when pushed through openings in the inner bottom panel flap.
  • the stops perform the desired retaining function, they can be employed only where they do not interfere with the mechanical locks holding the bottom panel flaps together. Thus they could not be used in a carrier which requires mechanical locks to be located adjacent the carrier ends.
  • the locking system which connects the bottom panel flaps together be capable of resisting forces caused by the weight of the packaged articles and by the stresses of shipping and handling which tend to pull the locks apart.
  • One approach to this problem utilizes primary and secondary locks.
  • the primary locks connect the flaps together, while the secondary locks function to hold the flaps in place in order to prevent the primary locks from separating.
  • a preferred locking mechanism is disclosed in U.S. Pat. No. 5,443,203, issued Aug. 22, 1995 in the name of Robert L. Sutherland.
  • the primary locks are integral with the outer bottom panel flap and the secondary locks are integral with the inner bottom panel flap, extending through openings in the outer bottom panel flap.
  • Each secondary lock is in the form of a tab separated by a fold line into a base portion and an end portion. The base portion overlies the end of the outer bottom panel flap and the end portion extends into a locking opening of the outer panel flap.
  • the structure of the secondary locks and the associated opening is such that the secondary locking tabs are prevented from being inadvertently withdrawn, thus not only maintaining the secondary lock in operative condition but also maintaining the primary lock in operative condition.
  • This locking arrangement does not permit employment of end stops since their location would interfere with the bottom panel locking tab structure.
  • the invention comprises a wrap-around article carrier containing a plurality of adjacent rows of articles, such as bottles, which have curved bottom portions.
  • Its basic construction includes the typical arrangement of side panels connected to a top panel and to a bottom panel formed of overlapped inner and outer bottom panel flaps.
  • the outer bottom panel flap includes an integral hinged retainer support tab adjacent each end edge of the outer bottom panel flap, the retainer support tabs being folded up from the outer bottom panel flap into the interior of the carrier.
  • the inner bottom panel flap includes an integral hinged article retainer tab adjacent each end edge of the inner bottom panel flap.
  • the article retainer tabs are folded up from the inner bottom panel flap into the interior of the carrier so as to engage the curved bottom portions of adjacent spaced articles and to engage the associated retainer support tab.
  • a locking tab adjacent each article retainer tab extends up through an associated locking opening in the outer bottom panel flap into the interior of the carrier and engages the associated retainer support tab.
  • both the article retainer tabs and the retainer support tabs are hinged to their bottom panel flaps along fold lines which are substantially parallel to the end edges of the bottom panel flaps.
  • the retainer support tabs include slots through which a corner of the locking tabs extend as a means of locking the assembly together.
  • the locking openings in the outer bottom panel flap through which the locking tabs extend are at least partially comprised of cutouts resulting from the inward folding of the retainer support tabs.
  • the locking openings preferably are partially comprised of slits extending from the cutouts as described in more detail below.
  • the retainer tabs include foldably connected side extensions which contact the curved bottom portions of adjacent articles, thus making the resulting retainer stops three dimensional.
  • the retainer stops fit snugly between the spaced bottom portions of the end bottles in the carrier and hold them in place against outward movement.
  • the stops interconnect the inner and outer bottom panel flaps they also reinforce any other locking means interconnecting the bottom panel flaps.
  • FIG. 1 is a pictorial view of a wrap-around bottle carrier which incorporates the mechanical locking features and the bottle retainer features of the invention
  • FIG. 2 is a plan view of a blank for forming the carrier of FIG. 1;
  • FIG. 3 is an enlarged plan view of the portion of FIG. 2 within the oval 3;
  • FIG. 4 is an enlarged plan view of the portion of FIG. 2 within the oval 4;
  • FIG. 5 is a pictorial view of the bottom portion of a carrier, with the bottles removed for the purpose of clarity, demonstrating the first phase of the formation of the bottom panel;
  • FIG. 6 is a pictorial view similar to that of FIG. 5, but showing the bottom panel flaps at a next intermediate stage of bottom panel formation;
  • FIG. 7 is a partial pictorial view illustrating the two different secondary male locking tabs in position to be inserted into secondary female locking openings
  • FIG. 8 is an enlarged transverse sectional view taken along line 8--8 of FIG. 7;
  • FIG. 9 is a partial pictorial view similar to that of FIG. 7, but illustrating the secondary male locking tabs in their final fully inserted positions;
  • FIG. 10 is an enlarged transverse sectional view taken along line 10--10 of FIG. 9;
  • FIG. 11 is a partial pictorial view of an erected retainer stop
  • FIG. 12 is a plan view of the retainer stop of FIG. 11;
  • FIG. 13 is a longitudinal sectional view taken along line 13--13 of FIG. 12;
  • FIG. 14 is an enlarged partial end view of a carrier showing the retainer stop in place between two bottles.
  • a wrap-around carrier 10 is illustrated in connection with the packaging of six beverage bottles B arranged in two rows of three each.
  • the carrier is comprised of side panels 12 connected at their lower ends to bottom panel 15 and at their upper ends to sloped shoulder panels 14, which in turn are connected to top panel 16.
  • the shoulder panels should be considered as part of the side panels.
  • Bottle neck openings 18 in the top panel and adjacent portions of the shoulder panels permit the necks of the bottles to extend through the top panel.
  • finger holes 20 which provide handle openings for lifting the carrier.
  • Foldable tabs 22 cover the finger holes when the carrier is at rest.
  • the side panels include heel cutouts 24 for receiving the outer bottom portions of the bottles, and the bottom panel 15 is comprised of overlapped inner and outer bottom panel flaps 26 and 28.
  • a bottle retainer or stop 30 extending up from the bottom panel 15 between the outer spaced curved portions of the end bottles B at each end of the carrier.
  • a blank 32 for forming the carrier is shown in FIG. 2, wherein similar reference numerals to those used in FIG. 1 denote similar elements.
  • the blank is rectangular in shape and includes straight edges, which makes for an efficient layout of the blanks in a web from which the blanks are cut.
  • Centrally located in the blank is top panel section 16, which is connected by fold lines 34 to shoulder panel sections 14.
  • the shoulder panel sections 14 in turn are connected by fold lines 36 to side panel sections 12.
  • Fold lines 38 which are interrupted by the heel cutouts 24, connect the side panel sections 12 to the bottom panel flaps 26 and 28.
  • the outer bottom panel flap 28 includes a locking panel section 40 which is connected to the main body of the flap 28 by fold line 42. Interrupting the fold line 42 opposite each heel cutout 24 are spaced slits 44 which form primary locking tabs 46. Located in the locking panel section 40 opposite each primary locking tab are slits which form secondary female locking openings. As best shown in FIG. 3, the centrally located slit 48 includes an outwardly extending arcuate portion forming a small retainer tab 50. Fold line 52 is outwardly spaced from the slit 48, and the ends of the fold line 52 and the slit 48 are connected by transverse slits 54, which extend slightly beyond the slit 48. This arrangement forms retaining tab 56 and is similar to the secondary female locking opening structure disclosed in U.S. Pat. No. 5,443,203.
  • the inner bottom panel flap 26 includes spaced secondary male locking tabs located opposite each heel cutout 24.
  • the centrally located secondary locking tab 58 is connected to the inner bottom panel flap by fold line 60.
  • the main body of the tab 58 is formed by slits 62 the ends of which are connected by fold line 64.
  • the fold line 64 is interrupted by arcuate slit 66, forming tab 68.
  • the secondary locking tab 58 includes a portion 70 formed by slit 72 which extends outwardly of the fold line 64.
  • a straight transverse portion 74 of the slit 72 forms a primary female locking edge which functions as explained below. This arrangement is similar to the secondary locking tab structure disclosed in U.S. Pat. No. 5,443,203.
  • the end secondary locking tabs 76 are different from the central locking tab 58.
  • the inner portions of the locking tabs 76 are somewhat similar to the structure of locking tab 58, having a fold line 78 corresponding to the fold line 60, slits 80 and 82 corresponding to slits 62 and 72, a straight slit portion 84 corresponding to slit portion 74 and an intermediate fold line 86 corresponding to fold line 64, thereby forming an end portion 87.
  • the outer portions of the locking tabs 76 are different.
  • Slit 88 connects the outer ends of fold line 78 and slit 84, and with slits 90 and 92 and fold line 94 forms retainer tab 30.
  • the fold line 94 is substantially parallel to the end edge of the blank and the slits 90 and 92 are extensions of the fold line 78 and the slit 84, respectively.
  • the slit 92 is shorter than the slit 90 in order to elongate the end portion 87 of the secondary locking tab 76, as explained further below.
  • Included in the retainer tab 30 are two arcuate fold lines 96 which extend from the ends of the fold line 94 and converge toward fold line 86 to divide the retainer tab into three sections, a main body section 98 and two side sections 100.
  • the structure of the end secondary locking openings is different from the central secondary locking opening.
  • the inner portion of the locking opening structure is similar to that of the central locking opening in that fold line 102 corresponds to fold line 52, end slit 104 corresponds to slit 54 and slit 106 corresponds to slit 48.
  • Fold line 102 and slit 106 are connected, however, by arcuate slit 108, which continues for a substantial distance beyond the slit 106 to form tab 107.
  • Slits 110 diverge from the ends of the slit 108 in the direction of the nearest end edge of the blank, and fold line 112 connects the outer ends of the slits 110.
  • each support tab includes an interior slit 116 which is aligned with the slit 106.
  • a blank is lowered onto a group of bottles to be packaged so that the necks of the bottles extend up through the bottle neck openings 18 in the top panel section.
  • the blank is then folded along the side panel fold lines and pulled tightly about the bottles in the usual manner so that the bottom panel flaps are overlapped.
  • the locking panel section 40 and the secondary locking tabs 58 and 76 are then folded back as shown in FIG. 5, which omits the bottles for the purpose of clarity, after which the locking panel section is folded down into the final position shown in FIG. 6.
  • the primary locking tabs 46 engage the edges of the cutouts formed by the slits 74 and 84 when the secondary locking tabs are folded back, and in their final position are located beneath the inner bottom panel flap 26.
  • the central secondary locking tab 58 is then pivoted forward about the fold line 60 and its outer portion 70 is folded about the fold line 64 to position the end of the outer portion 70 over the retaining tab 56 of the secondary female locking opening adjacent the tab 50.
  • This causes the tab 68 to separate from the slit 66 to form a cutout or retaining opening 118 of the same shape as the tab 68.
  • the secondary locking tab is then pushed toward the interior of the carrier, during which maneuver the tab 56 is free to pivot as necessary about its fold line 52 to permit the angular entry of the central secondary locking tab into the space created between the tab 56 and the edge formed by the slit 48 of FIG. 3.
  • the transverse slits 54 allow adjacent portions of the locking panel segment 40 to yield slightly to permit continued downward passage of the secondary locking tab.
  • the retaining tab 50 prevents the secondary locking tab from being forced out of the secondary locking opening, and at the same time the retaining flap 56 prevents the locking tab portion 70 from transversely moving, thereby maintaining the retaining tab in the recess 118.
  • the tabs 107 are free to pivot when this occurs, allowing the flap end portions 87 to enter at a slight angle. After entry the fold lines 102 of the tabs 107 cause the ends of the flaps 107 to be biased against the flap portions 87, which assists in maintaining the flap portions 87 securely in place.
  • the ends of the flap portions 87 pivot the retainer support tabs 114 about the fold lines 112 toward the interior of the carrier.
  • the ends of the flap portions 87 are positioned over the slits 116 of support tabs 114, as shown in FIG. 7, they also engage the solid portion of the support tabs 114 between the inner ends of the slits 116 and the curved slits 108, thereby pushing the support tabs 114 into the interior of the carrier.
  • the support tabs 114 overlie the retainer stop tabs 30 at the start of this procedure.
  • the inward pivoting of the support tabs 114 therefore causes the retainer stop tabs 30 to pivot inwardly about their fold lines 94.
  • the retainer side extensions 100 contact the adjacent bottles, which act as cams, causing the extensions to fold in, giving the retainer stop a three dimensional pyramidal shape.
  • the final condition of the retainer stop 30, the retainer support tab 114 and the end locking tab portion 87 is shown in FIGS. 11-13. Note that the outer corner 120 formed by the elongated upper edge of the end locking tab portion 87 has penetrated the slit 116 in the retainer support tab 114 so that the upper edge of the end portion 87 acts as a support for the support flap 114.
  • the retainer tab 30 Since the retainer tab 30 is supported by the support flap 114, it is securely buttressed. Further, since the corner portion 120 contacts the retainer tab 30, the end portion 87 of the secondary locking tab is prevented from being withdrawn from the interior of the carrier. In addition, as shown in FIG. 14, the squeezing of the retainer side extensions 100 against the sides of the bottles B also acts to hold the retainer stops in place.
  • the slit 92 is shorter than the slit 90. This results in angling the portion of the slit 88 that forms an edge of the outer tab portion 87, thereby forming the corner 120.
  • the invention permits the use of both article retainer stops and secondary locks designed to prevent accidental withdrawal of the secondary locking tab. Insertion of the end secondary locking tabs automatically erects the retainer stops, and at the same time moves the retainer support tabs into place. This cooperative relationship holds the end secondary locking tabs in place. Also assisting is the action of the tab 107 of the end secondary locking openings against the end secondary locking tabs. Fabrication of the carrier is simple and does not require extra steps beyond those normally associated with the use of secondary locking tabs incorporating an intermediate fold line.
